nara-eurrrn'e nacnnan citizen of the United States, residing at Budalo,in the county of Erie and State of New York, have inventedcertain newand useful Improvements in Hair-Cutting llllachines, of which thefollowing is a specifica- 4 tion.

My invention relates to hair-cutting devices and contemplates, as itsprincipal obrnent comprising multiple blades intelly formed and mountedwithin an operating casing. Is it is known to me that previdisposal of c.cut hair would be dispersed through the cutthen more clrly in a ousinventors have proposed to employ rotary and spiral-bladed cuttingelements for tonsorial purposes, I do not find that their improvementsare such as to lend the inventions readily to commercial exploitationand practical use.

Accordingly I have devised a cutter; of tapering formation as being bestadapted for actual service, as it may be then handled to the bestadvantage when clipping hair behind a customers ears or upon his-neck,exposing a cutting path of a width changeable to suit the condition in amanner not to be approached by a cutter of constant width, that is,untapered throughout length.

A second betterment of importance resides in the guard means fortheblade which makes a tapered sliding fit with its supports over theslot in the casing through which the blades 0 crate, allowingthe user ofmy device to tldJllSt the depth of cut by merely tapping the guard intothe desired position.

A third im rovement is evidenced in the lipped hair. Previously, the

ter blades inan indiscriminate shower. I

disclose means, however, for directing a stream of the severed hair awayfrom the operator or customer as fast as it is roved from the head, aswell as a construction of equivalent application but even greateradvantage, a receptacle which may be readily emptied of its accumulatedcontents.

The object of the invention being to attain the vantages set forth inthe foregoin, accomplishment of such object is made possible by theconstructions illustrated in the drawings we described in the fellowsspecification d out in the ole,

specification of Letters Patent. animation-area November ae, rare.serial We. came.

which are appended. hereto as a part of this application.

\ With reference to the drawings, wherein like characters of referencedesignate corresponding part throughout the several views,

Flgure 1 is a perspective of that embodiment of my hair cutting devicenew best known to me;

Fig. 2. is a longitudinal sectional View J through the casing; ject, theprovision of arotary cutter elethrough the casing and receptacle, and

Fig. 5 is-a similar view, but showing the receptacle replaced by achute-guard.

Referring primarily t Fig. 2, the tapered housing I employ is designatedby the numeral 10, and is shown as of aconical formation longitudinallyslotted and laterally increased in a centripetally tangential mannerdenoted by the numeral 11, to form the discharging. chute mouth 12'. Thelarger end of the casing is threaded into the socket cap 13 formedintegrally at the extremity of a handle shank 14. Similarly engaged withthe opposite end of the shank 14 is a hearing cap 15, preferably of someanti-friction metal.

'llhe cutter element is well illustrated in Figs. 2, 4 and 5, andincludes helically arranged blades 16, formed integrally with a centralhub portion 17 from a single piece of stock which is turned from asuitable tool is mounted in the handle cap '15 and is connected to theflexible drive means denoted by the numeral 21, which leads to a smallelectric motor or similar source of power.

The slot 22 provided longitudinally of the casing 10 permits the hair'toproject there through and into contact with the blades of the cutter..The amount of each cut may be gaged and regulated by means of a tapfitguide bar 23 which is provided with one cutting edge and is mountedthrough the socket cap 13 and a suitable bracket 23" at the small end ofthe casing. This bar is tapering and will obviously control theeffective opening of the slot 22 as it is adjusted by the operator to doso. i

Fig. 4 illustrates a receptacle for sheared hair which is laterallyextended from the cutter housing and to cover the chute mouth 12. Hinges24 mount this receptacle upon the casing and in conjunction with a sprmlip 25 permit the ready emptying thereo In Fig. 5 there is shown asupplementary guard 26 which overhangs the chute 12' and prevents hairfrom scattering, due to its acquired centrifugal force after beingsheared.

It is believed that the foregoing detailed description of my inventionas at present embodied will be ample to convey its mode of use andinherent advantages. The conical housing permits a skilful manipulationhitherto impossible with devices of this character. The tapered guidereadily controls the amount of the cut and the severed hair is neatlydisposed of by employment of either guard 26 or receptacle 25. Finallythe mechanical simpliclty of the integral cutter-blades, the journalingof the cutting element and the construction'in general are indicativeofadvantageous refinements offered throughout by the hair cutting deviceof this invention.

While in the foregoing, however, I have thus illustrated in the drawingsand described in this specification the form of the invention, as awhole and with its detailed embodiments, as at present constituted, Idesire to emphasize the fact that later adaptation of the device may bemade to meet concurrent changes in conditions of use without departingfrom the spirit of the invention as defined in the appended claims.

What is claimed is:

1. In a hair cutting device, a tapered cas- 1ng formed with alongitudinal opening, a bracket projecting from the casin adjacent theopening and a tapered guide lade slidable through said bracketand-having an oblique edge adap-tedto extend variably over said opening.

2. In a hair cutting machine, a tapered open-ended casing havln anentrance openmg and an exit openin ormed therein, end caps for thecasing, a ischarge spout leadng substantially tangentially from saidcasmg in proximity to said exit opening, cutting means moving betweenthe opemngs, a

regulating guide adjustable over the entrance opemng, a means to rotatesaid cutting element, and a receptacle supported by the spout over saidexitopening.

In testimon whereof I aflix my signature 1n presence 0 two witnesses. A
